The study considers Average Weighted Prime Lending Rate (AWPR) and Average Weighted Deposit Rate (AWDR), money supply as measure for country’s interest rates which supervise the behaviour of money market, Colombo Consumer price index as measure of inflation and exchange rates as the measure of external sector in economy of Sri Lanka. The objective was achieved by identifying the influence of macroeconomic variables on ASPI by using the statistical techniques of unit root test in order to fulfill the objective of stationary for all the macroeconomic variables and ASPI. The Johansen co-integration test was used to investigate whether the variables are co-integrated of the same order taking into account the trace statistics and the maximum Eigen-value tests. The variables were found to be co-integrated with at least one co-integrating vector. Finally, Vector Error Correction Model (VECM) was developed to forecast the long term behaviour. The results reveal that the change in average prime Deposit rate(AWDR), inflation rate (INF), exchange rate of Britain Pounds (GBP) and Japanese Yen (JPY), Special Drawing Right (SDR) affect All Share Price Index(ASPI) while money supply and average prime lending rate (AWPR) does not influence on ASPI. Moreover, all the macroeconomic variables and ASPI shows significant change and huge depreciation of currency in post war economy in Sri Lanka. From the results, it was inferred that the movement of ASPI reflect the macroeconomic condition of the country and can therefore be used to predict the future path of ASPI behaviour. Rapid growth in ASPI and decline in inflation and interest rates is observed in post war economy. The policy makers of the country should establish proper policies to control depreciation of the currency against USD, GBP, JPY and SDR in post war economy.

INTRODUCTION The dynamic relationship between macroeconomic variables and stock market returns is well-documented in the literature (Bilson et al, 2001 ; Gunasekarage et al, 2004; Husam et al, 2009). However, absence in the past literature related to examine the co- integration between macroeconomic variables and stock market’s sector indices returns in Sri Lanka. In Sri Lanka, Colombo Stock Exchange (CSE) consists of twenty sector wise price indices and macroeconomic variables may affect sector wise price indices differently. Also, these macroeconomic variables affect investment decisions and financing decisions in corporate sector. The stock exchange acts as the most important market for capital and companies get the ability to find sources of finance from the capital market. A well-developed capital market is essential to promote economic development in a country. The Sri Lankan government has been offering a number of incentives to enhance the share market. Specially, foreign investors are granted substantial incentives to invest in Sri Lankan company shares in budget 2016 (Ministry of Finance, 2016). Furthermore, companies listed in the CSE are already involved in the development of infrastructure in the country of the areas of Power and energy sector, Information technology sector and Telecommunication sector. Furthermore, banking and finance sector covers whole financial infrastructure in the country. Many researchers believe that investment influence on economic growth and economic development (Aydemir and Demirhan, 2009). Country’s business investment environment reflects by the stock exchange market which helps in distributing nation’s wealth by enabling wide ownership of public company stocks. Investors get an ability to buy shares of publicly listed companies which enable them to be the owners of the businesses and earn dividends according to their invested capital. Stock market performance is highly volatile to countries economic and political conditions. Theoretically, the interest rate has a negative impact on stock market performance because an increase of interest rate would evade investors making high risk stock market investments compare to low risk interest bearing security investments (French et al., 1987). Few related papers in a Sri Lankan context, focuses on examining impacts of macroeconomic variables on the stock market performance (Samarakoon, 1996; Gunasekarage et al., 2004; Wickramasinghe, 2011). However, these studies do not specifically focus on exploring the dynamic relationships between macroeconomic variables and sector indices performance in CSE. www.ijsrp.org International Journal of Scientific and Research Publications, Volume 7, Issue 12, December 2017 884 ISSN 2250-3153 Therefore, this study aims to explore the dynamic relationship between sector wise indices returns as a measure of performance of the industrial sector listed in CSE in Sri Lanka and macroeconomic variables. The theoretical motivation for undertaking the study on the effect of macroeconomic variables on stock prices returns and industrial index performance can be discussed as follows. The relations between exchange rate movements and share prices are based on the rise in the domestic interest rate. Upward movement in interest rates leads to capital inflows and therefore it makes the appreciation of exchange rate. This suggests that export dominant industries have a negative effect of reduction in exports and stock prices in such industries do not perform well. In contrast, currency appreciation boosts the share market for import dominant industries due to increase in imports. Also, whenever the interest rate on treasury securities increases, investors tend to sell stocks, causing stock prices to fall. The effects of inflation on the financial assets returns have been an important theoretical issue for many years. The basic theoretical concept in this area is commonly endorsed to Irving Fisher (1930) who stated that the nominal interest rate fully reflects the available information concerning the possible future values of the inflation rate. This hypothesis widely accepted among economists and has played an important role in the monetary economic theory, finance theory and macroeconomics. All the above considerations motivated to conduct the study in the Sri Lankan context for different industrial index performance. In finance, Arbitrage pricing theory (APT) is a general theory of asset pricing that holds the expected return of a financial asset can be modeled as a linear function of various macro-economic factors or theoretical market indices. Macro-economic factors and market indices are sensitive towards changes in pricing of the asset. Therefore, The APT essentially seeks to measure the risk premium attached to various factors that influence the returns on assets. Accordingly, Chen, Roll and Ross (1986), illustrated that economic forces effect on discount rates for the pricing of assets, also the ability of firms to generate cash flows, and future dividend payouts. This sense provided the basis for the belief that a long-term equilibrium existed between macroeconomic variables and share prices in CSE. 1.1.1 Colombo Stock Exchange The CSE has two main price indices called All Share Price Index (ASPI) and Standard and Poor Index (S&P). Index values are calculated an on-going basis during the trading session, with the closing values published at the end of each session. The CSE has 295 companies representing 20 business sectors as at 30th March 2016, with a Market Capitalization of Rs. 2,785 Billion in 2016 (Colombo Stock Exchange, 2016). Public Companies incorporated under the Companies Act No.7 of 2007 or any other statutory corporation, incorporated or established under the laws of Sri Lanka or established under the laws of any other state (subject to Exchange Control approval) are eligible to seek a listing on the CSE to raise Debt or Equity from public. In order to secure a listing of the company’s securities, they will be required to comply with the relevant provisions of the above act, the Securities and Exchange Commission Act No.36 of 1987 (as amended) and the Listing Rules of the Exchange (Security Exchange Commission, 2016). 1.2 Statement of Problem The financial markets are influential in the advancement of macroeconomic development and macroeconomic variables behaviour of an economy change the direction of financial market development. This is evident that well-developed financial markets encourage investors and corporations to increase saving and allocate capital to productive investments efficiently, which leads to an increase in the rate of economic growth. Therefore, stock market performance and macroeconomic variables behavior has been a popular topic for policy holders, corporations and investors where they need to find out whether there is a relationship among macroeconomic variables and stock exchange. It was concluded that macro economy and share market performance were the two most appropriate concepts for this study. Accordingly, the broad question
